Abstract
Description
- The present invention relates to a coreless roll of web material such as a toilet paper, and a method of forming the web material into a coreless roll.
- A conventional roll of toilet paper typically includes a core made of cardboard, while a toilet roll holder typically includes a pair of support bars which are inserted into the core to hold the roll in the toilet roll holder.
- There has recently been proposed a coreless roll of toilet paper. Such a coreless roll, however, tends to be collapsed when the toilet paper is almost exhausted from the roll. Referring specifically to Fig. 1, a conventional
toilet roll holder 2 includes arear wall 4 adapted to be secured to the wall of a bathroom, a pair ofside walls rear wall 4, and a cover 8 pivotably mounted to theside walls space 10 is defined by therear wall 4 and theside walls opposite support bars respective side walls toilet roll holder 2. The coreless roll of toilet paper 12 has a central throughbore 16. In use, the coreless roll 12 is inserted into thespace 10 from below thetoilet roll holder 2 so as to move thesupport bars support bars bore 16 of the coreless roll 12. After thesupport bars support bars toilet roll holder 2. When a desired length of toilet paper is withdrawn from the coreless roll 12, transverse forces act on the coreless roll 12. These forces tend to cause the coreless roll to collapse particularly when the toilet paper is exhausted from the coreless roll 12. In such a case, the roll drops from thetoilet roll holder 2. - United States Patent No. 4,487,378 discloses a coreless roll of a toilet paper with a bore having a polygonal cross section. First several windings of the toilet paper are moistured with water containing an adhesive or glue to facilitate maintaining of the shape of the bore and as a result, those windings are adhesively attached to each other to thereby prevent the roll from collapsing under the action of transverse forces. However, a disadvantage with this coreless roll is that those first several windings can not be withdrawn from the roll as they are firmly secured together.
- Accordingly, it is an object of the present invention to provide a coreless roll of web material which will not collapse under the action of transverse forces and which is able to be withdrawn until it is completely exhausted.
- Another object of the present invention is to provide a method of forming a web material into a roll without a core.
- According to one aspect of the present invention, there is provided a coreless roll of web material comprising a number of windings with a central through bore. At least the first two windings, for example, first 6 to 10 windings, adjacent to the central bore includes a plurality of circumferentially spaced lines of affixing means. These lines of affixing means extend in a direction transversely of the web material for releasably affixing at least the first two windings of the roll. Advantageously, the lines of affixing means resist transverse forces which act on the coreless roll when the web material is withdrawn from the roll. These lines of affixing means are spaced from each other along the circumference of the roll to facilitate release of the first two windings and enable complete withdrawal of the web material.
- In a preferred embodiment of the invention, the web material is a toilet paper. The coreless roll has a diameter of approximately 110 mm, and the central bore has a diameter of approximately 30 to 35 mm. The affixing means includes water. Alternatively, a glue in a diluted state may be used.
- According to another aspect of the present invention, there is provided a method of forming a web material into a coreless roll, which comprises the steps of feeding a web material to a substantially cylindrical mandrel with a plurality of axially extending projections arranged in a circumferentially spaced relationship, pressing a free end of the web material against the mandrel by a pressure roller for initial winding of a roll, applying affixing means to the pressure roller, pressing the web material between the pressure roller and the axially extending projections of the mandrel so as to transfer the affixing means from the pressure roller to at least first two windings of the roll, whereby the at least first two windings of the roll are releasably affixed together, winding the web material about the mandrel to provide a fully wound roll, severing the fully wound roll from the remainder of the web material, and removing the mandrel from the fully wound roll to render the roll coreless.
- These and other objects of the present invention will become clear from the following detailed description of preferred embodiments when taken in conjunction with the accompanying drawings.
- Fig. 1 is a perspective view of a toilet roll holder and a conventional coreless roll of toilet paper;
- Fig. 2 is a schematic view of a winding machine, showing the manner in which a web material is wound about a mandrel;
- Fig. 3 is a view similar to Fig. 2, but showing the manner in which a cutter is actuated to sever a fully wound roll from the remainder of the web material;
- Fig. 4 is a view showing the manner in which a jet of air is directed to the free end of the web material to initiate the winding of a roll;
- Fig. 5 is a perspective view showing the manner in which affixing means is evenly distributed on the pressure roller by means of a blade;
- Fig. 6 is a view similar to Fig. 5, but showing the manner in which affixing means is evenly distributed on the pressure roller by means of an air nozzle; and
- Fig. 7 is a perspective view of a coreless roll of toilet paper which has almost been exhausted.
- Referring now to Figs. 2 to 4, there is shown a winding machine suitable for forming a web material into a coreless roll. Specifically, a
winding machine 18 comprises a pair of drive orcontact rollers cylindrical mandrel 26 bears as shown in Fig. 4. A web material P is supplied from asupply roll 27 and wound into a roll about themandrel 26 to a predetermined thickness. To initiate winding of the roll, apressure roller 28 is lowered to press the leading end of the web material P against themandrel 26. A double-acting piston andcylinder assembly 30 is provided above thecontact rollers piston rod 32. Thepressure roller 28 is rotatably mounted to the lower end of thepiston rod 32 and lifted as the roll increases in diameter. When a predetermined length of the web material is wound onto themandrel 26 to form a roll R, apush rod 35 is extended from apusher 36 so as to move the roll R to the left in Fig. 2 and onto a pair ofroll receiving rollers pressure roller 28 is then lifted (as shown in Fig. 3) to allow for the placement of a new mandrel between thecontact rollers cutter 40 is actuated to sever the roll from the remainder of the web material. As shown in Fig. 3, the free or leading end of the continuous web material from thesupply roll 27 is rolled onto the new mandrel by means of anair nozzle 42. Thepressure roller 28 is again lowered to press the free end of the web material against the mandrel for initial winding of the roll. This mode of operation of the machine is well known in the art. - According to one feature of the present invention, the
mandrel 26 has a gear-shaped cross section and includes a plurality of axially extendingprojections 26a. Theseprojections 26a have a width of approximately 2.0 mm and are spaced approximately 3.0 mm from each other. Each roll R has a diameter of approximately 110 mm and has a hollow axial bore of about 30 to 35 mm in diameter. An affixing means is applied to at least first two windings of the roll, for example, first 6 to 10 windings, to releasably affix them together. Referring specifically to Fig. 5, a plurality ofspray nozzles 42 are arranged, at spaced intervals, above thepressure roller 28 and connected to afeed water line 44. Thefeed water line 44 is, in turn, mounted to thebracket 34 and connected to asource 56 of water. Ablade 46 is swingably attached to thebracket 34 and urged against thepressure roller 28 under the influence of a spring (not shown). Water as an affixing means is supplied from thewater source 56 and applied to the surface of thepressure roller 28 through thespray nozzles 42. The water is evenly distributed on thepressure roller 28 by means of theblade 46. As the web material is pressed between thepressure roller 28 and the axially extendingprojections 26a of themandrel 26, the water is transferred from thepressure roller 28 to the web material to wet at least the first two windings of the roll. The water serves to loosen the arrangement of fibers of the web material while the fibers are interwound under the pressure of thepressure roller 28. As the water is dried, the interwound fibers firmly affix these first two windings together. The first two windings of the roll can, of course, be released when the web material is pulled. Preferably, a plurality of lines L of affixing means are provided on the first 6 to 10 windings of a roll and extend in parallel to each other at spaced intervals. - As shown in Fig. 6, an
air nozzle 50 may alternatively be used to evenly distribute the affixing means on thepressure roller 28. Theair nozzle 50 extend along thepressure roller 28 and is connected to asource 51 of air under pressure. Theair nozzle 50 has anopening 52 through which air under pressure is directed to thepressure roller 28. The affixing means may alternatively include glue. The glue is preferably diluted about 10 to 20 times by means of a suitable diluent such as water.
